Re: music patterns and octave

[Gianmaria Lari]

Ciao David,

let's put it in another way. Have a look to the attached image and please suggest me how you would write the code to generate it.

Then please have a look to the code I *would* like to write to obtain it. Do you know if does exist anything similar to "\setOctave"? Do you see any logical mistake in trying to write it in this way? Sorry if the example is not very simple, but I have not been able to make it better.

\version "2.19.35"

\include "changePitch.ly"

rhythmPattern = {a16 \tuplet 3/2 {a8 a a} a16 a8 a4 a4} % a complex rhythm

scoreViolinI = \relative c'

{

  \setOctave c' %this command is just an example and it does not exist!

  \changePitch \rhythmPattern {c d d d c b d e}

  f g a b

  c d e f

  \setOctave c'  

  \changePitch \rhythmPattern {c d d d c b d e}

}

scoreViolinII = \relative c'

{

  \setOctave c' 

  \changePitch \rhythmPattern {a b b b a b a a}

  f f a a  

  c c f f

  \setOctave c' 

  \relative c' \changePitch \rhythmPattern {a b b b a b a a}

}

\score

{

  <<

    \new Staff \scoreViolinI

    \new Staff \scoreViolinII

  >>

  \layout { }

}

I don't know what the issue is that you "fixed".

Now here's a clue as to what you're trying to do. Looking at the
changePitch documentation, patterns are only used as the first
argument to a \changePitch function:
\changePitch pattern newnotes
Judging by its purpose, I would assume (short of testing it) that the
pattern has an _implied_ \relative{} around it.

What one doesn't do, but you are trying to do, is typeset the pattern
itself directly into a score. All that your examples here are doing is to
demonstrate the rules that LilyPond uses to interpret notes within
{ ... } \relative { ... } \absolute { ... }

So the pattern's notes themselves are never seen in the score: they're
replaced by the notes in the second argument (newnotes). That does
mean that we expect to see \include "changePitch.ly" in any compilable
examples you post.

Cheers,
David.
